Screening of rice germplasm lines against rice root-knot nematode Meloidogyne graminicola
2014
The rice root-knot nematodes infest rice plants and cause considerable yield loss to the tune of 17–30% to rice cultivation. In order to identify resistant source against them, 414 rice cultivars were tested by artificially inoculating fifteen-day-old pot-grown seedlings with 100 second stage juveniles. Only two entries from breeding lines, 127-28-1-1-1 & 183-6-1-1-3 were found resistant with score 2. Two lines from NBPGR collection and 4 aerobic cultivars were tolerant to root-knot nematode leaving all other in susceptible and highly susceptible category.
